" ZINC-MELTING APPARATUS.

Specification of Letters Iatent' Patented Aug, 13, 1918,

Application filed November 17,1915. Serial 110.61,!952.

To all whom'z't may concern Be it known that I, TAKEKICHI residing a No.6 Itabitsu-Mura, Kiku-Gun,

Fukuoka-Ken, Empire of Japan, have invented certain new and usefulImprovements in Zinc-Melting Apparatus, of which the following is aspecification.

This invention relates to an apparatus for melting zinc, particularly tosuch apparatus in which into a main tank a bottomless internal jacket issuspended leaving a space between tank and jacket. 1

It is the object of the present invention to provide an apparatusadapted for continuous operation allowing an exchange of the innerjacket without disturbance of the operation.

Another object of the invention is to be seen in the arrangement of showholes through which the operation may be observed at all times. i p

I In the accompanying drawing:

Figure 1 is a plan view of an apparatus constructed in accordance withthe present invention. v

Fig. 2 is a side view of the same.

Fig. 3 is a vertical section, and v Fig. 4 is a side View in sectionafter removal of the inner jacket.

In the outer tank 1 an inner, bottomless jacket 2 is suspended byresting with its flanges 3 upon the upper ed e of said tank.

3 Between both, the outer tan and the inner jacket, a free space 11 isleft, the lower part 4; of which is filled with lead upon which the zincto be melted is deposited within the limits of the jacket 2. It will beclear that the lighter zinc will float upon the heavier lead and will bemolten by the heat of said lead without commingling with the same. Theouter vessel is closed by a cover Gfitting also over the space 9 formedbetween both vessels near the top of the same.

At its corners the tank is somewhat widened as indicated at 10 so as toprovide show openings allowing the observation of the proper operationof the apparatus in ARAMAKI, engineer, a subj ectof the Emperor of Japan,

order to discover for instance a break in the jacket necessitatinganexchange of the same or other irregularities.

directl upon themolten lead, a hard meltmg su stance which has a highermelting polnt than the zinc, as for instance ordinary In order toprevent the air from actinglime 7 may be employed and placed over thesurface of the molten lead which occupies the space surrounding thesides of "the jacket 2. 8 are manipulating handles on the jacket adaptedto facilitate the working of the same and its removal.

What I claim is:

1. In zinc melting apparatus, an outer tank formed with comparativelyacute corners, an inner jacket provided with flange members adapted-tobe positioned within rounded corners thanthe tank whereby a space isprovided between the bottom and sides of the tank and jacket,,thedifferences in their corners resulting in a widened space at thesepomts.

2. In zinc melting apparatus, an outer' tank ,formed with comparativelyacute corners, an inner jacket provided with flange members adapted tobe positioned, within said tank and to be supported thereby by means ofsaid flange members engaging the upper edges of saidtank, said jacketbeing constructed shorter, smaller, andwith'more rounded corners thanthe tank whereby a space is provided between the bottom and sides of thetank and jacket, the diflerence in their corners resulting in a widenedspace at these points, and covers adapted to close intervening spacesbetween the tank and jacket between the flange members.

In testimony whereof I affix my signature inpresence of two witnesses.
